Question

The answer is NOT.. C. please help .

Answer 1

Option B

Explanation:

First term of the given arithmetic sequence 'a' = -3

Common difference in each successive term 'd' = -8 - (-3)

d = -5

Explicit formula for an arithmetic sequence will be,

`A_n=a+(n-1)d`

Here, n = number of term

`A_n` = nth term of the sequence

`A_n=(-3)+(n-1)(-5)`

For n = 23,

`A_(23)` = -3 + (23 - 1)(-5)

= -3 - 110

= -113

Option B is the answer.
